Pressure Sensor Calibration

Note
The pressure sensor is calibrated at the factory and should not require calibration.
Output Pressure Sensor Calibration
To calibrate the output pressure sensor, connect an external reference gauge to the output being calibrated. The
gauge should be capable of measuring maximum instrument supply pressure. From the Calibrate menu, select Pressure
Calib. Follow the prompts on the Field Communicator display to calibrate the instrument's output pressure sensor.
1. Adjust the supply pressure regulator to the maximum instrument supply pressure. Press OK.
2. The instrument reduces the output pressure to 0. The following message appears.
Use the Increase and
Decrease selections
until the displayed
pressure matches the
output x pressure.
Press OK when you have read the message.
3. The value of the output pressure appears on the display. Press OK to display the adjustment menu.
4. From the adjustment menu, select the direction and size of adjustment to the displayed value. Selecting large,
medium, and small adjustments causes changes of approximately 3.0 psi/0.207 bar/20.7 kPa, 0.30 psi/0.0207
bar/2.07 kPa, and 0.03 psi/0.00207 bar/0.207 kPa, respectively. If the displayed value does not match the output
pressure, press OK, then repeat this step (step 4) to further adjust the displayed value. When the displayed value
matches the output pressure, select Done and go to step 5.
5. The instrument sets the output pressure to full supply. The following message appears.
Use the Increase and
Decrease selections
until the displayed
pressure matches the
output x pressure.
